[Info-vax] Why doesn't PIPE work with freeware?

   Did you define DIRSORT as a foreign-command symbol, or what, exactly? 
Sometimes the results you get depend on your own (invisible/unreported)
actions.

   DIRSORT has a command-line parsing scheme which has some oddities. 
For example:

ITS $ mcr sys$disk:[]DIRSORT.EXE /version

                MCR by Lyle W West
                Version: V1.2-4 (Vax)
                Image Build: Sep 25 2022 (DecC)
                Required Privs: SYSPRV (or READALL)

   The program is not named "MCR", it's not running on a VAX, and the
compiler used is not called "DecC".

   I started to look into this mess, but haven't spent as much time on
it as it needs.
